To all whom it concern.- I

Be it known that I, ERASTUS E. WINKLEY,

a citizen of the United States, residing at Lynn, in the county of Essexand State of .Massachusetts, have invented certain new The presentinvention relates to sole-leveh,

ing machines, and more particularly to solelevehng machines of that typecom rising'a vibrating sole-leveling roll and a s oesupporting jack,such a machinebein r disclosed tate s No. 555,548, dated the 3d day ofMarch, 1896.

The object of the present invention is to provide an improved means foradjusting the jack and the mechanism for imparting relative longitudinaltraversing movements to the jack and sole-leveling instrumentalities forshoes of difierent sizes.

To thecabove ends the present invention consists of the devices andcombinations of devices, which will be hereinafter described andclaimed. V

The present invention is illustrated n the accompanying drawings, l11Wl11Gl1-- Figure 1 shows a side elevation of'a ma chine embodying thesame. "Fig. 2 shows the machine in front elevation.

j Similarreference characters will be employed throughout thespecification and drawings to designate corresponding parts.

In the drawings, A represents the frame,

,B theleveling-roll, and (I tl 1c "sh(lo-supporting i jack; all ctwhich, except as will be herein- "'after set forth, may be andpreferably are constructed and arranged as are the corre spending partsof the ntachine of the patent hereinbefore referred to, the presentmaehi ne it being understood, being provided with but a single roll andjack operated to level the soles of both right and left s'hoes.

In the present machine, inasmuch as there is but a single roll, which isused for leveling both right and left shoes, the change in the relativelateral inclination of the roll and jack is arranged to be controlled bythe operator, and this may be conveniently secured by providing thelaterally-tipping roll-carrier t with a laterally-projecting arm I),which is extended forward, as shown at b,-

and provided with a suitable handle b whereby asthe jack is oscillatedto carry the shoe beneath the vibrating roll the operator may PatentedJan. 22, 1907.

tip the roll-carrier-from side to side to adaptitto the/contour of thatpart of a shoe-sole at which it may be at any time operating, suchtilting," it being understood, occurring at different times iii-rightand leftshoea The means for'vibrating the roll and for holding it downin contact with the sole of the shoe are substantially the same as thatof the machine of the patent hereinbefore referred to, and reference maybe hadthereto for a full description thereof. a

In the present machine, like the machine of the patent, the jack'C ismounted upon a shaft 0', supported to oscillate in suitable bearings cof the frame A, and this shaft is automatically oscillated to cause thejack to have automatic movements predeterminedly varied inextent backand forth beneath the leveling-roll. ,The mechanism for imparting thesemovements tothe jack comprises an arm 0 which is aflixed to shaft 0, andwhich at, its lower end is slotted, as at c and reccives an adjustableblock 0 which is pivotally connected at, to a link a, which in turn ispivotallv connected at c to a lever c, I mounted on a shaftc", supportedin bearings shaftf carrying a pnlleyf driven by a belt from any suitablesource of power. The above arrangement is such that a rotation ofpinioIiF will drive the gear E and 'rotate. the shaft (1, thus rotatingthe c am D and through the lever 0 ljihk c andarm'ci oscillates thejackC baclfa'nd forth beneath,

the vibrating leveling-roll, "the path of the I00 cam D bein so formedas to im art'to"t'he jack forwar and backwardosc'il ations of a fixedand predetermined character, the oscillations varying in extent, so thatthe jack is moved back and forth beneath the leveling- 1o 5 roll in sucha manner as toenable the operator to mani ulatethe roll to cause it toproperly leve all portions of the sole. Itis necessary that .therelative longitudina'l traversing movement ofithe roll and. jack in;

in suitable bearings o the frame A, said be adjusted for shoes ofdifferent length, and such adjustment is secured byadjusting the block'0', to which the link 0 is connected, along the slot 0 in the arm a andin the machine of the drawings I have provided simple mechanismwherebythe adjustment of the jack to receive a shoe of a iven length willautomatically adjust the block 1: along the slot 0 to secure the desiredadjustment of the relative traversing movement of the roll and 'ack.

J As shown in the drawings, the ack C cornprises a bed e, at the forwardend ofwhich is affixed the toe supporting standard a. Mounted upon thebed 0 adjustment thereon is a heel-supporting standard e which has ascrew-threaded boss 6* extended into a slot in the bed e and engages athreaded shaft a, mounted in a longitudinal bearing formed in said bed.The shaft c is provided at one end with a handwheel a, by mean; of whichit may be turned,

as at its opposite end it carriesa bevel-gear e, which meshes with aried by the upper end of in a bearing e, supported by the arrnc, andwhich at its lower end is threaded, asshoivn at e, and engages athreaded bearihglin a swiveled block W, carried by the block 0 Theabove-descri bed arrangement is such that a turning of the shaft e toadjust the heelsupporting standard e atoward 'or from the toe-supportingstandar will, bymeans of the connecting mechanism described, effectacorresponding raising or lowering of the block 0 along the slot 0*, andthus adjust the 1011 itudinal rocking movements of the jack.

0 provide for the free play of the parts in making the adjustment of thejack and its connection with its actuating mechanism, the shaft e isformed in two sections, as shown, and connected by. a universal orgimbal joint e.

Like the machine of the atcnt, the drivin -shaft of the present mac inemay be provided with a suitable treadle-controlled clutch, whereby itmay be set in operation, and with automatic devices to stop itsoperation after one cycle of operation.

The 0 eration of the machine has been sufficient y described inconnection with the foregoing description of its construction and for alongitudinal.

a shaft 6 inouhtedarrangement, and afurther description thereof isdeemed unnecessary. j Having described the construction and 5 mode ofoperation of my invention, I claim as newand desire to protect byLetters Pat l entof the United States f 1. In a sole-leveling machine,the combinaj tion with a jack having toe and heel supports adjustablefor lasts of different length, of means for oscillating said jack withrelation to a tool for acting upon a shoesupported there- ;y, andsuitable shafts and connected mechanis'r'ri for simultaneously adjustingthe jack and its oscillating mechanism, substantially as descri bed.
